student needs to find the density of a cube. Each side of the cube measures 3 cm, and the mass of the cube is 12 g. What is the approximate density of the cube? 3 A 0.4 g/cm 3 B 2.25 g/cm 3 C 4.0 g/cm D 36 g/cm

A 0.4 g/cm³

Explanation:

The density of a substance, which is a cube in this case, can be calculated by using the formula:

Density = mass/volume

Where;

Density = g/cm³

Mass = grams

Volume = cm³

In this question, each side of the cube measures 3 cm. This means that the volume of the cube can be got by multiplying 3 × 3 × 3 = 27cm³. Hence, volume of the cube = 27cm³.

Mass of the cube = 12g

Density = 12/27

Density = 0.4444

Approximately, density = 0.4 g/cm³
